: Recent studies have shown that one-pot synthesis is a boon for triazines synthesis. One-pot processes had significant success in carrying out complex reactions under mild and eco-friendly conditions. One-pot synthesis is environmentally benign and more economical than other processes in triazines synthesis. The triazine scaffold has provided the starting key point for the design and development of pharmaceutical molecules with wide range of biomedical applications. This review highlights the various methodologies involved for one-pot synthesis of 1,3,5-triazine scaffolds.

Introduction: Quinoxalines show diversified applications in the field of medicinal chemistry. Materials and Methods: Therefore, we have designed a highly efficient, environmentally benign and one-pot protocol for the synthesis of 2-phenylquinoxaline from the reaction of Acetophenone, N-bromosuccinimide and 1,2-phenylenediamine under ultrasound irradiation in glycerol-water. Results and Discussion: We observed that, although the reaction efficiently completed in all of these solvents, the use of glycerol-water with different ratios gives consistently higher yields (89–94%) and decreases reaction times. Conclusion: The main advantages of this protocol are that it is a green method, avoids the use of toxic catalysts and volatile organic medium and the product is obtained with excellent yield.
